Is there a relationship between bike path access and cyclist injuries?

I was inspired by this CityLab article detailing the impending transportation crisis due to the MTA L Line shutdown. Specifically, I am interested in observing whether the shutdown contributes to an increase in cyclist injuries due to motor vehicle collisions as about 275,000 L Line riders seek alternatives.

NYC DOT has predicted about 2% of L Line riders to switch to cycling, while about 79% are predicted to move to other subway lines. I could investigate the dispersion of L Train riders to other options as a whole if data is available, but for now I will focus on cyclist safety as it’s more approachable with currently available data.

Now let’s look at some two-wheeled data.

And now a map of cyclist injuries and deaths over the last few years.
